Beta 11 - July 2019

This release is a final checkpoint before we land the C++ branch (cxx) into the master branch. We found there were a number of other small changes that needed to be made before the CXX and Master branches were ready to be merged, so we needed to do one more release before we did that.

Big Changes:

• The CXX branch is now up to date with master and will be landed shortly after we make this release. (#528)
• In keeping with the VFX platform, we've dropped support for python 3.5 and added support for python 3.7 in our unit test and CI system. (#526)

Small Changes:

• AAF bugfixes by @freesonluxo (#517, #518, #512, #493)
• Autogenerated schema documentation + unit test for detecting schema changes (#521)
• FCP XML bugfixes by @reinecke (#494)

Big thanks go to @andrewmoore-nz and @thecargocultnz for all the very detailed bug reports and repro cases, they are very helpful for improving OTIO robustness!
